Abstract

Abstract There are prepared compounds of the formulae ##STR1## where R and R 1 are saturated alkyl groups in which the sum of the carbon atoms in the two alkyl groups is 4 to 30 carbon atoms and wherein one of R and R 1 can be hydrogen, R 2 is hydrogen, lower alkyl with one to five carbon atoms, 2-hydroxyethyl, 2-hydroxypropyl, 2,3-dihydroxypropyl, benzyl,o-,m- or p-methylbenzyl, o-,m- or p-chlorobenzyl, o-,m- or p-bromobenzyl, aminoalkyl (C 2 to C 6 ), preferably aminoalkyl (C 2 and C 3 ), alkyl (C 1 to C 5 )-aminoalkyl (C 2 to C 6 ), 2-hydroxyethyl-aminoalkyl (C 2 to C 6 ), 2-hydroxypropyl-aminoalkyl (C 2 to C 6 ) or 2,3-dihydroxy-propyl-aminoalkyl (C 2 to C 6 ), R 3 in case the compound is present as the ammonium salt is hydrogen or a lower alkyl group with 1 to 5 carbon atoms, and X- is a monovalent, inorganic or organic acid group or one equivalent of a polybasic inorganic or organic group. The compounds are useful as antistatic finishing agents for thermoplastic synthetic resins.
